WebJan 5, 2024 · Hashing is a cryptographic technique that transforms any form of data into a special text string. For any given input, there is a deterministic output. When you put a plaintext into a hashing algorithm in simpler terms, you get the same outcome. Suppose you change anything about the input or the plaintext to the hashing algorithm. WebNov 29, 2024 · In cryptography, plaintext is usually ordinary readable text before it is encrypted into ciphertext, or readable text after it is decrypted.
